Application lled August 27, 1907. Serial No. 390,315.

To all whom it may concern:

Be it known that I, GEORG-.ii M. WASHING- TON, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new Figure 1 is a vertical sectional view of my limproved construction. Fig. 2 is a transverse vertical sectional view on the line 2-2, Fig. 1. Fig. 3 is a to plan view on a reduced scale. Fig. 4 is a siille elevation also on a reduced scale.

Similar numerals of reference denote'corres onding parts in the several views.

n the said drawing the reference numeral 1, denotes the upper half or section and 2 the lower half or section of the box, the saine being formed solid and centrally bored to reiceive the axle 3, the two sections being per manently unit-edby through bolts 4, a packing 5, being interposed between said sections.

The central bore receiving the axle 3 is formed large enough to receive a circular series of anti-friction rollers 6. intermediate laid axle and the interior wan of the said bore.

A The outer end ot' the central bore. is closed by a plate 7 permanently bolted into position by through bolts 8, a packing t) being interposed? ln the inner surface of said plate is an aiular groove 1() receiving the pintles '11 formed on the ends of the rollers 6, while lfixed in a central recess in said plate 7 is a retaining plate 12. the edges of said recess and 4retaining plate being oppositely inclined, as shown, to receive and retain a circular series v"anti-frictioi'i balls 13, against which the end of the axle 3 contacts. thus roviding an anti-friction end thrust for sait axle. The portion 10 left between groove 1() and the central recess on said plate T is in the shape ofan annular ring formed integral with said 'plate 7, and Aforming a bearing on one side for the rollers 6 and a bearing on its other side for the balls 13. -Said plate 7 is also provided )Vith an aperture 1/4 whereby a lubricant may be supplied to thc interior of the box.

The retainiiig bolts S extend completely throng-h the sections 1 and and serve to Specification of Letter-S'Patent.

Patented July 14, 1908.

similarly retain in position a plate 15 on ine inner face of the box, between which and the sections 1 and 2 is loca-ted a packing 1G similar to packing 9, said plate being cent-rally apertured to permit, the passage of the axle 3 and snugly .itting the saine. Said plate is annularly recessed at 17 on its inner face to receive the pintles 18 on the inner ends of rollers 6, an annular packing ring 19, forming the inner bearing for said pint-les, and serving to forni a tight joint around the axle 3.

ln a central annular groove in the sections 1 and 2 is located a series of absorbent rings 20 contacting with the rollers 6 and serving to carry the lubricant around the saine. i

From the above description it will be seen that l provide in a tightly closed box an antifriction side and end bearing for the axle, having' means for supplying a lubricant thereto in any desired quantity, the rings 20 serving to constantly distribute said lubricant around the roller bearings 6.

If desired I may provide plates 21 sliding in grooves in the sections 1 and 2, and retained in position by spring arms 22, the saine serving as a dust guard foi' the innei closing plate 15.

As shown in Fig. 2, the lower ends of bolts e that pass through the lower section 2 are threaded to engage said section and carry lock nuts on their lower ends.

Instead of the sections 1 and 2 being divided on a horizontal line, l prefer to separate them on diagonal lines oppositely disposed on opposite sides, as shown .in Fig. l, whereby any jars thereon will be better equalized and any tendency to displace the parts neutralized. l also prefer to employ a seiies Y of dowel pins 23 between the sections 1 and '.2 which serve not only to position thc .sections while being assembled but also aid to retain them in their relative positions.

Having thus described my invention what l claim as new and desire to secureby Letters Patent, is:

1. An axle box, embodying 'upper and lower solid sections centrally bored, end closing plates for said sections permanently fixed in position, one of which has an annular ring formed thereon, a series of' anti-friction rollers disposed longitudinally in said central bore and engaging bearing surfaces in het" of said end plates, and a series 01""'anti-ti'iction balls carried on the interior of the end plate formed with said annular ring, said ring forming a, bearing on one side tor said anti-'friction rollers and on its other side for ner plaie, eind eri annuler peeking ring in said anti-friction balls'. said recess forming the inner bearing for the 2. A11 axle box, embodying a easing een- I roller pirltles et that end.
